How much evidence says how much! This is his favorite sentence, he is a realistic version of the "Chinatown Detective" Qin Feng, and all the clues in the case can be insightfully observed by him.
He was meticulous in his handling of the case, devoted his life to finding the truth, and all he did in his life was to tell the perpetrator that if he tried the case, the truth would one day come out.
He is Li Changyu, a Chinese-American detective, and the American people affectionately call him "Dr.li."

A Chinese detective who went from Taiwan to the world was full of teachers, and everyone in the audience listened carefully to his analysis and views on the case.
It is precisely because of Li Changyu that criminal investigation can go to the world.
What kind of experience can shape such a perfect talent?
What made him sit in the top position in the U.S. police force?
How outrageous is his analysis of the case?
Let's walk into today's story and explore the legend of "contemporary Sherlock Holmes" Li Changyu.
<h1 class="pgc-h-arrow-right" data-track="10" > the thirst for knowledge as a teenager:</h1>
Li Changyu was born on November 22, 1938 in Rugao City, Jiangsu Province, his parents are business people, so Li Changyu grew up in a family with superior material conditions.
Later, because of his parents' business reasons, Li Changyu took his family to Taiwan.
Just two years after the family moved to Taiwan, Li Changyu's home has undergone great changes.
In January 1949, Li Changyu's father boarded a passenger ship from Shanghai to Taiwan, which was also quite famous, called the "Taiping Ship".
The ship collided with another ship on the way, most of the passengers on board lost their lives, and Li Changyu's father also died in the accident.
That year, Li Changyu was only 11 years old, and the death of his father caused the whole family to go downhill, and Li Changyu's mother, Wang Shuzhen, single-handedly supported the crumbling family.
At the most difficult time, Wang Shuzhen sold all her family property just to provide li Changyu with school.
Li Changyu has aspired to become a person who has contributed to society since he was a child, and he is well aware of his mother's suffering, so he studies very seriously.
At the age of 18, he entered the Central Police Academy in Taiwan with honors.
In the academy, he studied professional skills diligently, and finally graduated second in the class and was directly assigned to the Taipei Police Department.
After several years of hard work and outstanding achievements, Lee Chang-yu became the youngest sheriff in Taiwan's history.
However, when he deeply understood the criminal investigation and handling of cases, he found that his skills were still lacking, and he still needed to continue to learn.
In 1964, Li Changyu embarked on the road to study in the United States with a few suitcases and fifty dollars.
Because of the poor family situation at that time, Li Changyu never asked for a penny from his family, he worked half-time and studied half-time, and did many occupations in addition to studying.
Waiters in restaurants, security guards in banks, technicians in laboratories, etc., under this high-intensity pressure, Li Changyu achieved two and a half years of studying four subjects.
In the end, Li Changyu became a master's degree in biochemistry and molecular chemistry and a doctorate in biochemistry from New York University with perseverance.
After graduating, he was invited to teach at New Haven University in Connecticut, where he became a tenured honorary professor in just two years.
I remember once, an American policeman taunted Li Changyu's small eyes, and Li Changyu directly responded, Our eyes are small but we can see the evidence, and your eyes are big but you can't see anything.
Since then, the legend of the police circle belonging to Li Changyu has begun.
<h1 class="pgc-h-arrow-right" data-track="35" > his ability is enough to impress all the criminals in the world:</h1>
In the Clinton case, Clinton had just become president of the United States in 1993.
The case begins with a man named Vincent Foster, a member of the Clinton Presidential Campaign Committee.
One day a male corpse was found in a park in the United States, the deceased was Foster, from the scene investigation at that time, Foster was shot in the back of the head, there is a great possibility that he killed.
At this time, negative news about Clinton came from the POLITICAL CIRCLES in the United States, and they began to discuss whether It was Foster who Clinton killed.
Because there have been rumors that Clinton and Foster have a big difference in political views, if the speculation is true, then Clinton's presidency may be over.
In order to be able to investigate the truth as soon as possible, the US side directly sent Li Changyu to investigate, and Clinton urgently hoped that Li Changyu would be able to return his innocence.
At that time, the US police circles also said that the relationship between Li Changyu and Clinton was unclear, and the truth could be rewritten.
Li Changyu directly hit back: "How much evidence says how much." ”
After Li Changyu came to the scene of the case, he found that the scene had suffered serious damage, and it turned out that the US police had already conducted an investigation and destroyed the scene during the investigation, which made it more difficult for Li Changyu to detect.
The U.S. police only gave Li Changyu a few photos taken at the scene, and when Li Changyu came to the scene, he began to investigate on his own, looking for some remaining evidence, because he knew that the American police were unreliable.
The results also confirmed his idea that the photo was blurred and impossible to observe the current situation, so he began to use technical means to begin to restore the photos, and then judged by the trajectory of the bullet and Foster's fall.
In order to judge whether Foster committed suicide or not, Li Changyu began to carefully observe Foster's fingers, because the gun shooter would leave traces of gun smoke on his hands.
It turned out that Foster's fingers did contain something powdery, and Li Changyu initially judged that Foster was suicidal.
But how a person shoots himself in the back of the head becomes another question.
Lee Then Lee Chang-wook further verified, he proposed the hypothesis, Foster himself pointed the muzzle of the gun into his mouth and finally pulled the trigger.
In this case, Foster will have blood spurting from his mouth, and Foster's injuries do have blood stains, and it is indeed his own.
However, a hypothesis of the US police once again put the case into a mystery, the US police said that Foster's glasses are 6 meters away from people, which is impossible for normal people to fall to the ground, they said, this is Foster before death and fight with people, glasses were hit by the other side and eventually shot by others.
Li Changyu then did another experiment, and he found that according to his previous hypothesis, the glasses had a 30% probability of flying 6 meters away, but the glasses must be stained with blood.
However, after he got the evidence, he found that there was no trace of blood on the glasses, and he thought that his judgment would not be wrong, and it must be that the police had dropped the evidence.
So Li Changyu called all seven police officers at the crime scene that day, and then chatted normally first, and suddenly asked why did you drop your glasses?
As a result, a young policeman was questioned by Li Changyu, who also admitted what he had done, he said: "It was because I had no experience, and eventually destroyed the evidence, I left my fingerprints on the glasses because of negligence that day, and I cleaned the glasses out of panic." ”
Li Changyu then sent the glasses to the most advanced identification center in the United States for examination, and finally there were indeed residual blood stains on the glasses, and the case was successfully solved.
Lee Chang-yu relied on his step-by-step judgment to quell the Clinton incident, and after this battle, Lee Chang-yu became famous throughout the United States.
The Chicago Seven Murder Case was handled by Lee Chang-yu, and there is a restaurant in Chicago called Brown, which opens next to a gas station and closes at 9:30 every night.
One cold winter in 1993, the hotel manager who was supposed to go home at 10:30 did not come home, and his family could not get through how to call, so they chose to call the police.
The local police quickly rushed to the scene, only to find that nothing had happened and ignored it.
As a result, at two o'clock in the morning, the families of the seven employees of the hotel frequently called the police station, and the police also understood the seriousness of the matter, so they came to the scene and broke the door of the hotel.
When I went inside, all seven employees were shot and frozen in the freezer.
The US FBI directly dispatched a special task force to investigate, the result was not a clue, and finally at the request of the Chicago police chief, Li Changyu came out.
Li Changyu began to conduct a site survey and perform an autopsy on the body, but there were no useful clues, and suddenly he saw the garbage can.
As he rummaged through the trash cans, he said that the trash cans, like surveillance, can tell something unknown.
So he found the bill of the day in the trash can and checked the consumption record of the day.
He found that the last list was written with two loaves, a fries and four pieces of fried chicken, and Li Changyu began to think, and he found that the murderer did not eat chicken breast.
He then analyzed it based on racial preferences and finally deduced that the perpetrator should be a Hispanic.
After that, the U.S. police launched an arrest, and after decades, there was no result, but the DNA of the criminal was preserved at that time.
During a 2007 drug crackdown, A drug dealer arrested by U.S. police coincided with the Chicago Seven-Man Massacre more than a decade ago, and the investigation found that the man was indeed a Hispanic.
Li Changyu's prophecy came true again, and this was the Divine Detective.
